FAQ
- Who knows, the difference between plate flange and hubbed flange in the application.
- Welding plate flange for general medium.Hubbed flange suitable for the inflammable and explosive, corrosive, toxic high placesThe sealing surface of flange plate are raised face (RF), hubbed flange sealing surface can be used from surface, convex surface, tongue and groove face.The two structures are different, the sealing effect is not the same, the strength is not the same.
- please detail the flange parameters. 10Also, can you tell me where the flange reference standard should be downloaded?
- I. WN100 (B) -16RF S=6WN is a neck welding flange, 100 is nominal diameter 100mm, (B) is the use of metric tube (also known as GB), 16 nominal pressure is 16MPa, RF is sealed type, sudden surface seal, S=6 is steel pipe wall thickness.
- What does the flange 20592-MFM stand for?
- MFM refers to the upper and lower flange of the matching structure of the sealing surface, is the concave convex surface of the matching: M is convex, FM is concave.
- What's the difference between RF flange and RJ flange?
- The difference between the RF flange and the RJ flange is that the seal is different.RF flanges are flat sealsRJ flange is steel ring seal
- Oil seal flange
- Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations. A gasket is a ring made of a material that produces plastic deformation and has a definite strength. Most from the non metal plate gasket is cut down, or by professional plant size, the material for the asbestos rubber sheet, asbestos board, polyethylene plate; also useful thin metal plate (Bai Tiepi, stainless steel) asbestos nonmetal materials such as wrapping made of metal gasket; and a belt around and asbestos tape made of thin steel and the spiral wound gasket. The ordinary rubber gasket for temperature lower than 120 DEG C; asbestos rubber gasket is suitable for steam temperature lower than 450 DEG C, the oil temperature is below 350 DEG C, the pressure is lower than the 5MPa of the occasion, for general corrosive medium, is the most commonly used acid asbestos board. In high-pressure equipment and piping, copper or aluminum, steel 10, stainless steel lens or other shapes of metal gasket. The contact width of the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket have higher processing finish. Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different. According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad. 1. to classified material of carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PPC etc..
- What is the function of the flange stub?!
- Different pressure flanges have different thicknesses and use different bolts. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
- How many kinds of flanges do you have? Does anyone know a more specialized classification?
- Welding plate flange (PL)Hubbed flange (SO)Neck welding flange (WN)Threaded flange (TH)Socket welded flange (SW)Flange cap (BL)These are the main, there is a key to say, is the sealing surface classification
- For flange who is more detailed explanation? For example, how to position?
- The flange of the material according to the production of material can be divided into: WCB (Tan Gang), LCB (low temperature Tan Gang), LC3 (3.5%, WC5 (1.25% chromium nickel steel) 0.5%, WC9 (2.25% Cr Mo steel), C5 (5%), C12 (% Cr Mo) 9% Cr 1% mo (4), CA6NM (12% steel) CA15, (4) (12% CR), CF8M (316 stainless steel, CF8C (347) CF8 (stainless steel), stainless steel 304), CF3 (304L stainless steel), CF3M (316L stainless steel), CN7M (alloy steel), M35-1 (Meng Naier), N7M (Haast B, CW6M nickel alloy nickel alloy (Hasta) C (CY40), Inconel) flange connection (flange, joint) composed of a pair of flanges, a gasket and a plurality of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure. Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations.
